Serving as executive producer on Halo 5: Guardians, Lee has been with 343i since 2009, starting on Halo 4. Prior to this, Lee held several positions within Microsoft Game Studios.

The appointment comes as Microsoft confirm that Halo 6 will not be shown at this years E3, which also looks to be the big reveal for the Project Scorpio console and its initial line up. However, Microsoft community manager Brain Jarred did state that there would be "a little something" to show, and that it would not be an anniversary edition of Halo 3. The title will be ten years old this September.
